Description

Technical Field

[0001] This utility model relates to the field of continuous casting auxiliary devices, specifically to a high-efficiency continuous casting setter vibration device. Background Technology

[0002] Continuous casting, short for continuous steel casting, is a casting process where a continuous casting machine mainly consists of an tundish, a crystallizer, a vibrating device, a dummy bar, a secondary cooling channel, a casting machine, and a cutting machine. The specific process of continuous steel casting is as follows: molten steel continuously passes through a water-cooled crystallizer, solidifies into a hard shell, and is then continuously pulled out from the bottom outlet of the crystallizer. After being cooled by water spray and completely solidified, it is cut into billets. The vibrating device's function is to drive the crystallizer to vibrate and prevent the molten steel from sticking to the inner wall of the crystallizer.

[0003] Existing vibration devices have the following shortcomings:

[0004] 1. Existing vibration devices are generally strip-shaped structures, and there is a lack of devices that can vibrate circular crystallizers.

[0005] 2. Due to factors such as billet thickness, crystallizer material, and cooling conditions, the amplitude requirements of the above factors are also different, and there is a lack of devices that can adjust the amplitude of circular crystallizers. Utility Model Content

[0006] The purpose of this invention is to provide a high-efficiency vibration device for a continuous casting setter.

[0028] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0030] Reference Figures 1 to 5 As shown, a high-efficiency continuous casting setter vibration device includes a base, which is horizontally positioned.

[0031] It also includes a housing 1, a rotating cylinder 2, a top plate 3, a drive assembly, a rotating assembly, several sliding assemblies, and several lifting assemblies. The housing 1 is vertically arranged, and the interior of the housing 1 is integrally formed with a receiving cavity. The rotating cylinder 2 is rotatably arranged on the top of the receiving cavity. The drive assembly is located between the housing 1 and the rotating cylinder 2. Four L-shaped rods 4 are fixedly arranged on the outer wall of the housing 1 in the circumferential direction. Each lifting assembly is inserted into one L-shaped rod 4. The top plate 3 is fixedly arranged between several lifting assemblies. A support plate is fixedly arranged inside the rotating cylinder 2. The rotating assembly is located on the support plate. Several sliding assemblies are located on the rotating assembly.

[0032] Reference Figures 1 to 5 As shown, the drive assembly includes a first motor 5, a gear 6, and a gear ring 7. The gear ring 7 is fixedly mounted on the top outer wall of the rotating drum 2, the first motor 5 is fixedly mounted on the outer wall of the outer casing 1, and the gear 6 is fixedly mounted on its output end. The gear 6 meshes with the gear ring 7. During operation, the device is first placed at the bottom of the crystallizer, and the tops of several rubber pads 24 are kept in contact with the outer wall of the crystallizer. Then, the first motor 5 is started by the controller, so that its output end drives the gear 6 to rotate clockwise. Since the gear 6 meshes with the gear ring 7, the gear ring 7 is fixedly connected to the rotating drum 2, and the rotating drum 2 is rotatably connected to the receiving cavity inside the outer casing 1, thereby driving the rotating drum 2 to rotate counterclockwise.

[0033] Reference Figures 1 to 5 As shown, the rotating assembly includes a second motor 8, a driving pulley 9, a driven pulley 10, and a belt.

[0034] 11. A rotating shaft 12, a turntable 13, and several connecting rods 14 are included. A second motor 8 is fixed on the outer wall of the support plate. A drive wheel 9 is fixed on its output end. The rotating shaft 12 is rotatably mounted on the top of the support plate. A driven wheel 10 is fixed on the rotating shaft 12. A belt 11 is sleeved between the drive wheel 9 and the driven wheel 10. The turntable 13 is fixed on the rotating shaft 12. The connecting rods 14 are hinged to the bottom of the turntable 13. When it is necessary to adjust the vibration amplitude, the second motor 8 is started by the controller, so that its output end drives the drive wheel 9 to rotate. Since the driven wheel 10 is fixedly connected to the rotating shaft 12, and both the rotating shaft 12 and the turntable 13 are fixedly connected to the rotating shaft 12, the drive wheel 9 and the driven wheel 10 are sleeved by the belt 11, thereby driving the turntable 13 to rotate.

[0035] Reference Figures 1 to 5As shown, each sliding component includes a push block 15, a slider 16, a first trapezoidal block 17, a second trapezoidal block 18, and a third trapezoidal block 19. Several grooves are evenly spaced on the outer wall of the rotating cylinder 2. Each slider 16 is slidably disposed inside one groove. The push block 15 is fixedly disposed at the bottom of the slider 16 and is hinged to the end of the connecting rod 14 away from the turntable 13. The first trapezoidal block 17, the second trapezoidal block 18, and the third trapezoidal block 19 are evenly spaced at the top of the slider 16. The height of the first trapezoidal block 17 is less than the height of the second trapezoidal block 18, and the height of the second trapezoidal block 18 is less than the height of the third trapezoidal block 19. Since the bottom end of the turntable 13 and each push block 15 abut against both ends of each connecting rod 14, and the push block 15 is fixedly connected to the slider 16, it drives the connecting rod 14 to rotate. Since each slider 16 is slidably connected to a groove, the push block 15... Block 15 is fixedly connected to the bottom of slider 16. Push block 15 is hinged to the end of connecting rod 14 away from turntable 13. First trapezoidal block 17, second trapezoidal block 18 and third trapezoidal block 19 are designed at equal intervals on the top of slider 16, so that the second trapezoidal block 18 or the third trapezoidal block 19 slides onto the rotation path of roller 21. Thus, when the drum 2 rotates, the rotation of the second trapezoidal block 18 or the third trapezoidal block 19 will cause it to come into contact with roller 21. This contact force is then transmitted to roller 21 and connecting block 22, further driving the lifting rod 20 to rise, thereby realizing the vibration of top plate 3. Since the height of the first trapezoidal block 17 is less than the height of the second trapezoidal block 18, and the height of the second trapezoidal block 18 is less than the height of the third trapezoidal block 19, the lifting stroke of roller 21 and lifting rod 20 can be adjusted, thereby adjusting the vibration amplitude of top plate 3 to achieve a three-level adjustment effect.

[0036] Reference Figures 1 to 5As shown, each lifting assembly includes a lifting rod 20, a roller 21, and a connecting block 22. The lifting rod 20 is fixedly mounted on the bottom of the top plate 3 and is slidably connected to the L-shaped rod 4. The connecting block 22 is fixedly mounted on the bottom of the lifting rod 20. The roller 21 is rotatably mounted on the connecting block 22, and the outer edge of the roller 21 is in contact with the top of the rotating drum 2. In the initial state, the first trapezoidal block 17 is located on the rotation path of the roller 21. Therefore, when the rotating drum 2 rotates counterclockwise, it drives the first trapezoidal block 17 located on it to rotate counterclockwise. When the inclined edge on the first trapezoidal block 17 contacts the roller 21, the roller 21 begins to climb. When the roller 21 is pushed up by the slope, it rises. At this time, the roller 21 will drive the lifting rod 20 to rise on the L-shaped rod 4 through the transition block 22. When the roller 21 climbs from the inclined side to the top of the first trapezoidal block 17, it is the highest position of the roller 21 and the lifting rod 20. When the roller 21 disengages from the first trapezoidal block 17, the lifting rod 20 changes from rising to falling. This process completes one vibration. As long as the rotating drum 2 continues to rotate, the top plate 3 can be driven to vibrate back and forth through the lifting rod 20, thereby causing the crystallizer to vibrate, preventing molten steel from sticking to the inner wall of the crystallizer, which is conducive to improving the initial forming efficiency of the billet.

[0037] Reference Figures 1 to 5 As shown, a return spring 23 is fitted on the outer wall of each lifting rod 20. The L-shaped rod 4 and the adapter block 22 abut against the two ends of the return spring 23 respectively. Since the L-shaped rod 4 and the adapter block 22 abut against the two ends of the return spring 23 respectively, the return spring 23 can push the adapter block 22 each time the roller 21 disengages from the first trapezoidal block 17, so that the roller 21 carried by the adapter block 22 can quickly return to the top of the rotating drum 2 and be in contact with it, so as to ensure the vibration effect of one time.

[0038] Reference Figures 1 to 5 As shown, several rubber pads 24 are evenly spaced on the top of the top plate 3. The rubber pads 24 serve to shield and protect the crystallizer from direct contact with it when the top plate 3 vibrates, thus preventing damage to the crystallizer.

[0039] Reference Figures 1 to 5 As shown, two bearings 25 are symmetrically arranged on the inner wall of the receiving cavity. The inner ring of the bearing 25 is fixedly connected to the outer wall of the rotating cylinder 2. When the rotating cylinder 2 rotates, the two bearings 25 play a supporting and limiting role, ensuring that the rotating cylinder 2 can rotate smoothly inside the receiving cavity, which is beneficial to improving the contact effect with the roller 21.
